Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed January 24, 1918. Serial No. 213,481.

To all whom it may concern:

Be it known that I, CHRISTIAN G. FiLznn, acitizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon- Torches; and I do hereby declare the following to be a full, clear, and exact description of the invention', suoli as will enable others skilled in the art to which it appertaiiis tolmake and use the same, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to hydro-carbon torches ofthe type shown and described in my prior Letters-Patent Nos. 1,204,967 and 1,204,968, issued November 14, 1910, and consists in certain improvements in filter mechanism and hinged connection mechanism hereinafter particularly described and ypointed out land illustrated in the accompanying drawings, in which:

Figure 1 1s aside elevation of a hydrocarbon torch embodying my invention.

Fig. 2 is a plan view of a fragment thereof showing the spring suspension of the hinged connection.

Fig. 3 is an enlarged horizontaleentral lsection of the same.

Fig. 4 isa'side elevation of a portion of thesanie' looking in the direction of the Varrow in Fig. 3.

Fig. 5 is an enlarged vertical central -scction of a fragment of the torch mechanism. Fig. 6 is an enlarged side View of my vimproved vapor lter tube.

Fig.v71is an enlarged cross sectiony of the same through one o'f the filter openings in "the .wall thereof.

' In these drawings A, indicates the liquid fuel container, A', indicates an air pump by meansof which the desired pressure is maintained in the container; B, indicates the ltube C", all of said parts being of ordinary construction as shown and described in my above 'mentioned patents.

Connected to the housing B is a tube D which leads into a tube D at right angles thereto (see Fig. 3) from which a tube (l extends at right angles to the tube D, and parallel with the tube D, terminating in fa short tube E which is at right angles to the tube (Z, and parallel with the tube D.

The interior of the tube E is chambered out, as shown at e in said Fig. 3. against the open end of the tube E is a tube F', the axis of which is in alinement with the axis of the tube E. The tube F is provided with aii annular collar which projects into the chamber c and forms a journal bearing for the tube F t0 rotate upon. The tube F is cliambered out as shown at 7" in Fig. 3, and from the tube F a tube F extends at right angles to the axis of the chamber f', and will swing in the plane of the axis of the tube D. lVithin the duct e and chamber f there is a bolt G which fits an opening f3 leading into the chamber f and is provided with threads g which engage the threads in the opening f2 and is adapted to hold the tube F in place in the tube E. Upon the sciew-threaded end of the bolt G I place a jam-nut G which prevents the bolt G from turning on the threads in the opening The tube F is also provided with a stud F2 in which one end of a coiled spring H which is wound around the extension F is secured, the other end of said spring engagingthe tube D as shown. From the foregoingit will be seen that the tube F is transversely hinged or pivoted upon the tube E and swings within the plane of the axis of the tube D. To permit liquid fuel to flow through the ducts d, cl, and I provide a clearance at the opening f3 into the chamber f preferably by cutting a 'flat surface g on the bolt G, as shown in Figs. 3 and 4,. This however may be accomplished in any other suitable manner. The clearance thus provided should not be greater than the diameter of the jetopening in the jet-tube hereinafter described, so thatv the fluid passing there through will be strained and any particles Abutting of solid matter which may be in the liquid r I fuel which will not pass through said jet opening will not pass throughj said elearance space. Secured in the duct f of the tube F is the tube c of the return-bend connectionf'C (see Fig. 5) with which tube cthe tube b of the generator is connected in the usual man ner. Upon the tube c is supported the vapor jet-tube C having a fine jet-opening c in the front end thereon, the interior thereof being enlarged sufficiently to receiveithe inner of the iiltentube and support it concentric with the `Wall o f the counterbored ch'ai'n'bercgfinl-s'aidf-jet'- The rear end ofthe Jetftube, t V1s closed by means of a screw plu'gI'Which07m tube C.
